Bests & Worsts Reviews from Amazon

I just received my order for the 564xl black cartridge. In the listings on Amazon it showes two ink cartridges, one for under $22.00 and states its the new size printing up to 2x more pages, and another for under $30.00 which is listed as the older cartridge that prints up to 3x pages. Well I took the trouble to make sure I ordered the old cartridge with 3x pages. You guested it, I received the newer cartridge which sells for under $22 and was charged for the older cartridge. Amazon you need to update your listings. If I had known I could have bought the new smaller cartridge locally, it was cheaper at my office supply store. I won't be ordering again, I will buy locally for now. (I ordered product # HP CB321WN and received CN684WN)
